Patented July 3, 1906.

Application filed October 2,1905. Serial No. 280,992.

Be it known that I, EvERETT GEORGE KAUFMAN, a citizen of the United States, and a resident of Yonkers, in the county of l/Vestchester and State of New York, have invented a new and Improved Razor-StroppingMachine, of which the following is a full, clear, and exact description.

The invention relates to razor-stropping machines in which the strop is manually actuated to rock a shaft connected with the clamp employed for holding the razor in contact with the runs of the strop.

The object of the invention is to provide a new and improved raZor-stropping machine, more especially' designed for stropping ordinary handled razors and arrangedto permit Convenient insertion and removal of the razor and to insure an easy rocking motion of the razor-clamp to bring the cutting edge of the razor-blade into proper contact with the runs of the strop.

The invention consists of novel features and parts and combinations of the same, which will be more fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure l is a sectional plan view of the improvement. Fig. 2 is a side elevation of the same, part of the frame being broken out; and Fig. 3 is a longitudinal sectional side elevation of the same on the line 3 3 of Fig. 1.

The frame A of the raZor-stropping Inachine is preferably made rectangular in crosssection, and in the sides A and A2 of the said frame are journaled the rock-shafts B and C, connectedwith each other by arms B and C, linked together, so that' when the rockshaft B is caused to rock the other rock-shaft C rocks in unison with the rock-shaft B.

On the rock-shaft O is secured a razorclamp D, preferably in the form of two pairs of spring-jaws, for receiving and holding the heel of the blade E of the razor E, having the usual pivoted handle E2, as plainly indicated in Fig. 1.

In order to permit convenient insertion and removal of the razor while in a closed position, the inner end of the frame A is open and the side A of the frame is provided with a recess or cut-out portion A3 adjacent to the open inner end to permit of passing the razor when in a closed or folded position through the recess A3 into the casing and to engage the razor-blade E with the razor-clamp D. After the razor-blade E is inserted in the clamp D the operator can swing the handle E2 into an open position, so as to leave the blade E within the frame A and in working position. In a like manner when it is desired to remove the razor the handle E2 is swung into a closed position, and then an outward pull is exerted to withdraw the blade E from the razor-clamp D. Thus an ordinary razor can be readily inserted and removed while in a folded position, thus preventing injury to the cutting edge of the razor during the inserting and removing operation, at the same time eliminating all danger of the operator cutting himself during said operation.

The strop F 'for stropping the razor is passed over the rock-shaft B, so that the opposite runs extend on opposite sides of the razor-blade E', and when the operator alternately pulls on the ends of the runs of the strop F then the latter in traveling over the rock-shaft B rocks the samealternately in opposite directions, and as the rock-shaft O rocks in unison with the rock-shaft B it is evident that the razor-blade E is swung alternately in engagement with the inner faces of the runs of the strop F, thereby stropping the cutting edge ofthe razor-blade.

In order to prevent the strop F from interfering with the interlinked arms B and O, a guard G is provided, held within the frame A to inclose the said linksm with a view to prevent the strop from engaging the said links, especially when the same swing into an angular position, as indicated in Fig. 3. The guard G is extendedinto the inner open end of the frame A to form a stop for the free end of the razor-blade E. (See Fig. 1.)

The sides A and A2 of the frame A are connected with each other at their outer ends by a tie-rod H, on which lits a thimble H', abutting with its ends against the inner faces of the sides A and A2, so as to hold the same prop IOO erly spaced apart, and thereby prevent binding of the rock-shafts B and C in the said sides A and A2 of the frame A. The outer ends of the tie-rod H are formed into eyes H2, engaged by a bail I, adapted to be connected with a hook J or other similar means attached to a wall or like support, as plainly illustrated in Figs. V1 and 2. By the arrangement described the frame A is free to swing when using the device in stropping the razor-blade E', as above explained, so that undue binding of the Working parts is completely prevented.

The raZor-stropping machine shown and described is very simple and durable in construction and is not liable to get easily out of order.

Having thus described my invention, -I claim as new and desire to secure by Letters Patent- 1. A raZor-stropping machine comprising a frame open at the inner end and having in one of its sides a recess adjacent to the said o en inner end for the insertion and removal of the razor While in a closed position, a tierod connecting the frame sides at the outer end of the frame, a bail connected with the said tie-rod outside of the frame ends, rockshafts j ournaled in the frame sides and provided with arms linked together to rock the shafts in unison, a razor-clamp secured on the rock-shaft located adjacent to the open inner end of the frame, and a razor-strop engaging the other rock-shaft to rock the same.

2. A raZor-stropping machine comprising a frame open at the inner end and having in one of its sides a recess adjacent to the said open inner end for the insertion and removal of the razor while in a closed position, a tierod connecting the frame sides at the outer end of the frame, a bail connected with the said tie-rod outside of the frame ends, rockshafts j our-naled in the frame sides and provided with arms linked together to rock the shafts in unison, a razorclamp secured on the rock-shaft located adjacent to the open inner end of the frame, a razor-strop engaging the outer rock-shaft to rock the same, and a guard in the said frame inclosing the said linked arms.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

EVERETT GEORGE KAUFMAN.
